A ball pen designed to have an ink consumption of 0.64 to 1.6 mg per cm , which feels good in writing while attaining the rapid-drying properties of the ink transferred to a paper surface and the nondrying properties of the ink at the tip of the ball pen. The ball pen employs an ink in which the content of water has been regulated to a value in the range of from 30.0 to 80.0 wt. %, the content of a volatilization inhibitor has been regulated to a value in the range of from 0.1 to 10.0 wt. %, and the content of a sparingly volatile, water-soluble, liquid solvent has been regulated to a value in the range of from 1.0 to 40.0 wt. %. La présente invention concerne un stylo à bille dont la consommation d'encre est de 0,64 à 1,6 mg/cm , agréable à la main, se distinguant par la rapidité du séchage de l'encre transférée sur le papier et par le non séchage de l'encre à la pointe du stylo. Ce stylo à bille utilise une encre dont la teneur massique en eau est maintenue dans la plage des 30% à 80%, pour une teneur massique de l'inhibiteur de volatilisation maintenue dans la plage des 0,1% à 10%, la teneur du solvant liquide hydrosoluble modérément volatil étant maintenue dans la plage des 1% à 40%.
